Is this library kismet or something? I've had a VERY chatty patron stop mid-sentence, and look from me to a coworker, then back and ask, "Do you two call eachother in the morning and decide what to wear?"

In the summer, our library actually institutes "apparel" day. We pick a theme and then everyone tries to dress accordingly. Sometimes, we even do a twin thing where you find a buddy and come up with an appropriate twin theme. It is usually a lot of fun and creates bonding.
